>Description:
The following test failure occurred:
sscanf_whitespace: [0.001968s] Failed:
/usr/src/lib/libc/tests/stdio/t_scanf.c:71: c == 'z' not met
The corresponding test code of interest is as follows:
ATF_TC(sscanf_whitespace);
ATF_TC_HEAD(sscanf_whitespace, tc)
{
atf_tc_set_md_var(tc, "descr", "verify sscanf skips all whitespace");
}
ATF_TC_BODY(sscanf_whitespace, tc)
{
const char str[] = "\f\n\r\t\v%z";
char c;
/* set of "white space" symbols from isspace(3) */
c = 0;
(void)sscanf(str, "%%%c", &c);
ATF_REQUIRE(c == 'z');
}
